Almonds

Whether you're tossing them into a salad or eating them by the handful — these nuts are an excellent source of monounsaturated fat. They're also considered an excellent source of protein, vitamins (such as thiamin, riboflavin, and E) and minerals (think: copper, iron, and zinc). And the benefits don't stop there. According to study published in the British Journal of Nutrition, almond consumption lowers cholesterol.

Asparagus

Not only is this vegetable packed with anti-inflammatory nutrients, it contains high levels of folic acid — which can assist in the regulation of your moods by releasing a neurotransmitter called "serotonin" into your system. But if the feel good powers of asparagus aren't enough to sway you, maybe its anti-cancer benefits will. Research published in the international journal Cancer Letters suggests that the consumption of asparagus may halt the formation of cancerous tumors.

Avocados

Theses super fruits are packed with heart-healthy monounsaturated fats, and are excellent carriers for the fat-soluble vitamins A, D, E and K. Research has not only linked avocado consumption to improved cardiovascular health and blood sugar regulation, but a 2009 study published in the journal Nutrition and Cancer suggests that avocados have anti-cancer benefits (specifically in the prevention of cancers of the mouth, skin and prostate).

Berries

Whether you're eating black berries loaded with antioxidants that improve brain functioning, or blueberries packed with vision-protecting vitamin C, it's hard to go wrong by adding one of these super foods to your diet. But if the high vitamin and antioxidant intake isn't appealing enough, recent research published in the Journal of Medicinal Food found that berries (specifically strawberries, raspberries and blueberries) have properties that can help lower your risk of breast and cervical cancer.

Black Beans

Nutrient-packed and cheap? That's the one-two punch offered by these legumes. In fact, according to research from the University of Guelph in Ontario, black beans have similar heart healthy, cancer-preventing compounds typically found in berries, tea, and red wine. What's more, you'll receive a beneficial protein-fiber combination each serving.

Broccoli

This cruciferous vegetable is not only high in vitamins C and K, it's stacked with the phytochemical indoles and sulforaphane, which many consider to be anti-cancer nutrients. But the benefits of broccoli aren't limited to cancer. Research in the Journal of Agricultural and Food Chemistry found that broccoli has the potential for protecting the cardiovascular system.

Butternut Squash

This winter squash is low in calories and high in vitamin C. But more importantly, it's loaded with beta-carotene and beta-cryptoxanthin. That might be a mouthful, but according to research published in Cancer Epidemiology, Biomarkers and Prevention, those who consume foods rich in beta-cryptoxanthin have a lower risk of developing lung cancer.

Chicken Breast

Boneless, skinless chicken breast is a timeless classic. Not only is it an excellent source of lean protein, but it's a terrific source of coenzyme Q10, which essential for skin cell turnover.

Edamame

This popular Japanese soybean is not only rich in vitamins C and B, but it is one of the few natural sources of vitamin E. Edamame is also a great source of protein, says Jeffrey Blumberg, Ph.D., director of the antioxidants lab at Tufts University. These beans are considered a natural source of antioxidants and isoflavones.

Eggs

Consider this near the top of the list for ultimate super foods. After all, what else can brag about being low in price, high in protein and available year round.

Flaxseed

Whether you're sprinkling it onto your cereal or blending it into your smoothie, this powerful plant can provide an abundant source of fiber, magnesium and calcium. These seeds also contain extremely high levels of lignans (which is an abundance of micronutrients and omega-3 fatty acids) and have been linked to the prevention of numerous health problems. In fact, according to a study published in the Archives of Internal Medicine, flaxseed, due to its high fiber content, can help prevent heart disease.

Garlic

Although you may not snack on garlic cloves the way you snack on almonds, this herb is a must-have on your shopping list. This hearth-healthy herb not only reduces your body's cholesterol and triglycerides, it protects blood cells and blood vessels from inflammatory and oxidative stress. As an added bonus, research published in the American Journal of Clinical Nutrition found that compounds in garlic may prevent cellular changes that may lead to cancerous tumor development and inhibit tumor growth.

Onions

Onions, just like garlic, are both rich in sulfur-containing compounds — so they may not be good for your breath, but they're good for your body. Multiple studies have shown that eating onion can have cardiovascular benefits (mainly protection against heart attacks) when being consumed in a diet packed with other vegetables.

Spinach

"Whether it's spinach, kale, or romaine lettuce, leafy greens are some of the most nutrient dense foods on earth," says Chris D'Adamo, Ph.D., a nutritional epidemiologist at the University of Maryland school of medicine. So toss it in your salad or serve it as a steamed side, as an excellent (low-calorie) way to get your daily dose of vitamin K. Still need convincing to eat your greens? According to research published in the International Journal of Cancer, consuming spinach protects against the occurrence of aggressive prostate cancer.

Salmon

This fish is top of the class in terms of health benefits. Salmon is a great go-to source for lean protein and packs a hearty dose of heart-healthy omega-3 fatty acids. In fact, research published The Journal of the American Medical Association found that consumption lowers the risk of death from heart disease. "But if you can, try and purchase wild-caught salmon," says D'Adamo. "Farm-raised salmon often has food coloring added to make it pink and is loaded with antibiotics."

Sweet Potatoes

Eating sweet potatoes can be an easy fix for packing in the nutrients for your diet. They're not only loaded with complex carbohydrates and phytochemicals, sweet potatoes are an excellent source of fiber, beta-carotene, as well as multiple vitamins. And considering vitamin A is the most important vitamin for protecting your vision and keeping your eyesight strong, numerous studies have drawn a parallel between the consumption of this sweet vegetable and healthy eyes.

Tomatoes

Loaded with antioxidants, low in calories, and packed with anti-cancer benefits — tomatoes can be considered a triple threat when it comes to fruits. They're also high in lycopene, which may promote cardiovascular health and helps prevent skin from sun damage, says D'Adamo. And the benfits don't stop there. Research published in the journal of Cancer Epidermal Biomarkers Prevention shows that regular consumption of this power fruit can help lower the risk of prostate cancer in men.

Yogurt

The best way to eat dairy and lose weight? Research points to yogurt as more potentially more powerful than milk. Numerous studies have linked the consumption of yogurt to better digestive health as well as an overall lower percent of body fat. "But make sure to check the labels" says D'Adamo. "Certain yogurts can contain a lot of sugar. So your best bet may be to buy Greek yogurt."
